* As a simple matter of code hygiene, in particular to aid in checking for
leaks, ddsperf should free all memory it allocates on exit.
* Remove spurious mutex unlock in ddsperf
* Removing a participant means removing one or two entries from the "pong
writers" array ("pong wr"), and there it read 1 element beyond the end
of the array while moving the remaining elements forward.
* Constant-rate pinging was broken because of two reasons, one worse than
the other:
* setting the rate had a mismatch in variables (publication rate and
command-line argument) resulting in a completely wrong ping interval;
the code now has a bit more clear variable naming ...
* the timing of the pings was relative to the current time, but the
wakeup a little delayed, resulting in a lower rate than requested.
It now simply adds the ping interval to the scheduled ping time, rather
than the time at which the ping is being sent. To guard against really
late wakeups, rates that are too high, suspending the machine, &c. it
will in extremis delay the next ping.
